摘要

In some applications of opinion mining in text, it is important to distinguish what an author is talking about from the subjective stance towards the topic. Therefore, it needs to find the relation between sentiment expression and target. This paper proposes a novel method based on dependency grammars to mine the relation. In this method, the process of mining the relations is turned into a procedure of searching in the dependency tree of a sentence. The result of our experiments shows that word dependency relation based methods is more flexible and effective than some previous surface patterns based methods.
